摘要：

The Mg-Al-Mn (AM) based cast alloys were optimized for balanced tensile properties (strength and ductility) and reasonable response to heat treatment. 1-3% tin addition was found to be effective in strengthening the AM alloys due to the precipitation of Mg2Sn phase in the Mg-Al-Sn (AT) alloys. The new AT72 (Mg-7%Al-2%Sn) offers a well balanced strength and ductility as well as good corrosion resistance. T5 (artificial aging after as-cast condition) is recommended for additional strengthening effect of AM and AT alloys.
